some more details ...

i inquired with the company who runs this approx 3 months back, and they said that they already had successful trials in march - april, but because of monsoons they did not get permission from govt and told me that they will again start in Sept.

You can try inquiring again on the number mentioned in Contact Us page in above link. Also update here if you get any more information.

They appear to be up and running. There is even an online booking option. However, the online booking form requires a middle name, you have to fill it in. And you have to state what kind of ID you will provide. I don't have a middle name and if I make one up it won't match my passport which will be my ID. I have tried the contact form and email. They steadfastly refuse to reply to either.
